here are the answers to the multiple-choice questions:
1. A system of numbered squares formed by vertical and horizontal lines drawn on the map represents:
- C) Grid references
- Grid references use a network of numbered squares to pinpoint locations on a map.
2. A collection of symbols used to represent both natural and human features found on a map is called?
- C) Conventional signs
- Conventional signs are standardized symbols used on maps to represent various features.
3. When enlarging a map twice its original size, what happens to the new scale?
- A) It is divided by two
- Enlarging a map means that the features appear larger, so the map covers a smaller area in more detail. This implies a larger scale (e.g., 1:50,000 enlarged twice becomes 1:25,000, where the denominator is divided by two).
4. An indication of industrial function on a map is:
- A) Works
- The term "Works" (e.g., Iron Works, Water Works) on a map typically denotes an industrial site or facility.
5. Which colour is used to identify water body on a map?
- C) Blue
- Blue is the conventional color used on maps to represent water bodies such as rivers, lakes, and oceans.
6. The most convincing proof to show the spherical shape of the earth is?
- C) Circumnavigation
- The ability to travel continuously around the Earth and return to the starting point is a direct and convincing proof of its spherical shape.
7. Which of the following is NOT an importance of Great Circles?
- C) They are used for the calculation of distance on the map
- Great circles represent the shortest distance between two points on a sphere and are used for actual distance calculation on the Earth's surface and for air routes. Map distances are calculated using the map's scale, not directly by great circles.
8. The season in the Northern Hemisphere when the sun is over head at the tropic of cancer:
- A) Summer
- The sun is directly overhead at the Tropic of Cancer (23.5° N) around June 21st, which marks the summer solstice in the Northern Hemisphere.
9. Identify the main inputs into the hydrological cycle.
- D) Precipitation and solar energy
- Solar energy is the primary energy input that drives evaporation, and precipitation is the main input of water from the atmosphere back to the Earth's surface.
10. An example of human interference in the hydrological cycle is?
- A) Cloud seeding
- Cloud seeding is a deliberate human activity aimed at modifying precipitation by introducing substances into clouds.
11. Which of the following is characteristics of the troposphere?
- D) Temperature decreases with increase in height
- In the troposphere, the lowest layer of the atmosphere, temperature generally decreases with increasing altitude.
12. The six's thermometer provides the following information about temperature EXCEPT;
- D) Mean annual body temperature
- A Six's thermometer measures maximum and minimum air temperatures. Mean daily, monthly, and annual air temperatures can be calculated from its readings, but "mean annual body temperature" is unrelated to atmospheric measurements.
13. The height of land above sea level refers to;
- B) Altitude
- Altitude is the vertical distance or height of a point on the Earth's surface above mean sea level.
14. Which of these is a characteristic of a hot desert climate?
- A) Cloudless skies
- Hot desert climates are typically characterized by very clear, cloudless skies, leading to high daytime temperatures and significant nocturnal cooling.
15. A mixture of minerals and organic material that occupy the upper most layer on which plants grow is called?
- C) Soil
- Soil is the uppermost layer of the Earth's surface, composed of minerals, organic matter, water, and air, which supports plant growth.
16. Drought can be caused by:
- D) Deforestation
- Deforestation can contribute to drought by reducing local rainfall, increasing surface runoff, and decreasing the soil's ability to retain moisture.
17. The most environmental friendly way to handle waste is by
